At a glance

Parses a math modeling contest problem from PDF, Word or pasted text and produces a task breakdown, paper outline, scoring map and model route for each question.

  • Works in 5 steps: 文档读取 → 题意解析 → 数据条件解析 → …
  • Starting work on a modeling contest problem given as a PDF or Word file
  • SKILL.md covers 全局流程协作约束(长对话防漂移), 执行契约, 目标 and 阶段流转, plus 13 more sections
  • Runs Python scripts from its folder; calls python

What it does

Given a competition problem as a PDF, Word or text file, or as pasted text, the skill extracts the task type, data conditions and constraints of each sub-question and recommends models along with a validation plan. Attachment data files and your own emphases or limits can be supplied as optional extras. It reads from a problem_files folder and writes into paper_output/step1.

Four deliverables are required. A is a one-page alignment of each question's inputs, outputs, metrics, constraints and ways to verify; B is a paper outline; C is a table mapping scoring points to evidence and paper location; and D is a model route with baseline, improvements, validation and risks. The skill is not a standalone entry point: it runs a workflow_guard.py check, records progress through a context-memory skill and hands off to later modeling and orchestration skills. If problem_files is empty it stops and asks for the problem.

When your agent uses it

  • Starting work on a modeling contest problem given as a PDF or Word file
  • Deciding which model each sub-question should use and how to validate it
  • Aligning a paper outline with the contest's scoring points

Example prompts

  • “Analyze the contest problem PDF in problem_files and give me the model route for each question.”
  • “Read this problem statement and produce a paper outline with a scoring-point table.”
  • “I am unsure how to model question two, so list baseline, improvement and validation options.”

Requirements

  • Python
  • Contest problem files in a problem_files folder
  • The paper-workflow-orchestrator skill from the same package

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 文档读取
  2. 题意解析
  3. 数据条件解析
  4. 模型选型引擎(规则优先,结合提示式决策)
  5. 验证与鲁棒性

What it can do on your machine

Read from SKILL.md and the folder at commit 7712876. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Math Modeling Problem Analyzer loads about 1.4k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

解析赛题PDF/Word,抽取任务与数据条件并给出模型选型与验证路线。Invoke when用户提供赛题文档或题目文本,需要确定采用何模型/方法。

赛题文档自动解析与模型选型

全局流程协作约束(长对话防漂移)

  • 本 skill 不得作为孤立入口。用户要求完整论文、生成 Word、继续流程或不确定阶段时,先回到 paper-workflow-orchestrator 判断当前 S0-S8 阶段。
  • 启动或继续本 skill 的正式任务前,必须运行:
    bash
    python .trae/skills/paper-workflow-orchestrator/scripts/workflow_guard.py --skill problem-doc-model-selector
  • 如果输出 [WORKFLOW FAIL] 或报告 status != "PASS",停止本 skill,按 paper_output/qa/workflow_guard_report.json 的失败项回补前置阶段,不得凭记忆继续。
  • 本 skill 只写入自己契约范围内的 paper_output/ 产物;完成后必须回到 paper-workflow-orchestrator 判断下一步,并用 context-memory-keeper 记录已完成产物、阻塞项和下一步。
  • 长对话中如果上下文变长、阶段不确定或用户分开调用 skill,先运行:
    bash
    python .trae/skills/paper-workflow-orchestrator/scripts/workflow_guard.py --status
    再读取 paper_output/qa/workflow_guard_report.json、paper_output/preflight_report.json、paper_output/input_manifest.json、paper_output/results/run_manifest.json 和本 skill 的上游 JSON 契约,按报告里的 recommended_skill 与 next_action 继续。
  • 继续流程前,必须把 paper_output/context/workflow_memory.json 视为长期断点记录;若其中的 current_step、next_step、recommended_skill 与 workflow_guard.py --status 不一致,以 guard 报告为准。
  • 每次完成本 skill 的产物后,先回到 paper-workflow-orchestrator 或运行 workflow_guard.py --status,再更新 workflow memory:
    bash
    python .trae/skills/context-memory-keeper/scripts/update_workflow_memory.py
    更新后读取 paper_output/context/workflow_memory.json / .md,确认下一步和推荐 skill 已记录。

执行契约

  • 上游输入:problem_files/ 中的赛题 PDF/Word/TXT 和附件数据。
  • 必须输出:paper_output/step1/problem_analysis.json,以及 A_题意对齐.md、B_论文大纲.md、C_评分点对齐表.md、D_模型路线.json。
  • 下游交接:modeling-paper-rubric-and-model-selector 读取 problem_analysis.json 生成模型路线;完整 workflow 由 paper-workflow-orchestrator 串联。
  • 推荐下一步:完成题意分析后进入 modeling-paper-rubric-and-model-selector;如果用户目标是完整论文,回到 paper-workflow-orchestrator 判断后续阶段。
  • 失败回退:若 problem_files/ 为空,应停止并提示补齐赛题;若部分文档无法解析,保留可解析内容并在输出中记录字段画像缺失。

目标

  • 输入赛题 PDF/Word 文档或题面文本,自动抽取“每一问”的任务类型、数据条件与约束,并输出贴题的模型选型与验证路线。
  • 生成评分友好型交付:一页纸题意对齐、论文大纲、评分点对齐表、模型路线(基线/改进/验证/风险)。

阶段流转

  • 解析完成后,不要停留在“是否满意”的泛泛询问;应说明已生成的题意契约,并给出下一推荐阶段。
  • 若用户意图是完整论文,在输出 A/B/C/D 后回到 paper-workflow-orchestrator,由总入口决定继续生成模型路线、数据计划、QA 和正文。
  • 拒绝偷懒: 必须输出完整的 A/B/C/D 四部分,不得省略。

适用时机

  • 用户提供赛题 PDF/Word 或题面文本,需要快速判断各问应采用的模型/方法并制定实验验证计划时。
  • 对题意理解不确定、模型路线拿不准或需要论文结构与评分点对齐建议时。

输入

  • 赛题文档路径或题面全文(支持 PDF、DOCX、TXT)。
  • 可选:附件数据文件路径、你希望强调的亮点或限制。

输出

  • A 一页纸题意对齐:逐问给出输入/输出、评价指标、关键约束、可验证方式。
  • B 论文大纲:摘要、问题重述、假设、符号、数据说明、模型、求解、结果、检验、结论、不足、参考。
  • C 评分点对齐表:评分点 → 证据形式(图表/实验/检验)→ 论文位置。
  • D 模型选型与路线:每问的任务类型、最小可用基线、改进路线、验证计划、风险与备选。
  • E 数据需求配置 (可选):若发现题目需要外部数据(如人口、气象、经济数据),自动生成或更新根目录下的 data_requirements.json,以便 authoritative-data-harvester 自动获取。
  • 机器可读契约:paper_output/step1/problem_analysis.json,包含 documents、data_files、questions、recommended_models、validation_plan、figure_suggestions 等字段,供模型路线、证据审计、正式写作和总编排器继续读取。

目录约定(与项目全局对齐)

  • 赛题与附件统一放在 problem_files/。
  • 建议把本技能的四类输出归档到 paper_output/step1/(例如 paper_output/step1/A_题意对齐.md 等),便于后续技能引用。
  • 同步生成 paper_output/step1/D_模型路线.json,用于保留每一问的模型路线、验证方式和建议图表。

脚本入口(推荐)

本 skill 已内置结构化分析脚本:

bash
python .trae/skills/problem-doc-model-selector/scripts/analyze_problem.py

该脚本会扫描 problem_files/,读取 TXT/Markdown/DOCX/PDF 赛题文本,并对 CSV/XLSX/XLS 附件做轻量字段画像。成功后会写入 paper_output/step1/problem_analysis.json,后续模型路线、证据门禁和正式 outline 均以它为上游契约。

前后衔接

  • 后续通常先做:data-cleaning-and-visualization(数据清洗与可视化)。
  • 若要继续到论文草稿:回到 paper-workflow-orchestrator。

约束(必须遵守)

  • Memory Interaction (必做):
    • 开始前,检查 memoryskill.md 中是否有外部文献/数据索引(如 g-sci 提供的参考文献),将其纳入模型选型依据。
    • 完成解析后,必须调用 context-memory-keeper,将“核心任务类型”、“数据条件”与“模型选型结论”更新到 memoryskill.md 的 Short-term Workbench 中。这是后续产文技能获取上下文的关键。
  • 外部数据检查 (必做):
    • 若解析发现题目依赖外部公开数据(如“搜集相关数据”、“附件数据不足”),必须生成 data_requirements.json 并写入根目录。
    • 配置内容应包含明确的 url(若已知)或 manual_search 提示,并将 active 设为 true。
  • 本技能输出的题意对齐与模型路线,必须能被后续写作定位引用;建议固定归档到 paper_output/step1/。
  • 若用户目标是“最终论文可提交”,本技能完成后不得直接进入产文阶段,必须先保证数据口径可用:进入 data-cleaning-and-visualization 或补充 authoritative-data-harvester。
  • 若用户不想分步推进,必须回到 paper-workflow-orchestrator 执行完整 workflow,避免“解析完成但未生成正文”的断档。

工作流程

  1. 文档读取
    • PDF:优先 PyMuPDF,否则 pdfplumber;保留图表标题与小节编号。
    • Word:python-docx;保留段落与表格结构。
    • 清理:去页眉页脚、合并断行、标准化单位(cm⁻¹、% 等)。
  2. 题意解析
    • 规则抽取“问题1/问题2/问题3…”与“附件说明/单位/关键参数”。
    • 识别任务类型:预测/分类/评价/优化/聚类/仿真/机理建模。
    • 提取约束与边界:入射角、层次关系、单位口径、可行域。
  3. 数据条件解析
    • 附件文件名与字段:列名、单位、样本量、范围、缺失值比例。
    • 结果口径:需要反射率、厚度、误差、排名或资源分配等。
  4. 模型选型引擎(规则优先,结合提示式决策)
    • 预测类:移动平均/指数平滑/回归/ARIMA → 树模型/LSTM。
    • 分类类:逻辑回归/朴素贝叶斯 → 随机森林/梯度提升,不平衡用代价敏感。
    • 评价与排序:规范化+加权和 → 熵权/CRITIC/AHP/TOPSIS/VIKOR。
    • 优化与调度:线性/整数规划 → 多目标与启发式(遗传/退火)。
    • 聚类:K-means/层次 → GMM/DBSCAN(噪声与非凸形状)。
    • 机理/仿真:微分/差分/系统动力学;与数据驱动对照。
    • 物理/工程建模:根据领域知识建立方程(如热传导、流体力学、电路分析、光学传播),利用最小二乘或优化算法进行参数反演与模型修正。
  5. 验证与鲁棒性
    • 指标:RMSE/MAE/AUC/F1/MAPE/轮廓系数/约束满足率。
    • 交叉验证/滚动回测/留出法;消融实验与敏感性分析。
    • 极端/边界情景与单位口径一致性检查。

判别逻辑速查

  • 出现“预测/估计未来/趋势/参数估计”→ 预测类。
  • 出现“分类/是否/风险等级/识别”→ 分类类。
  • 出现“综合评价/排序/权重/打分”→ 评价与排序。
  • 出现“资源分配/路径/选址/成本最小/收益最大”→ 优化与调度。
  • 出现“分群/画像/相似性/模式发现”→ 聚类。
  • 出现“机理/仿真/动力学/微分方程”→ 机理/仿真。
  • 出现“物理过程/化学反应/信号传输/力学结构”→ 物理/工程建模。

输出模板

  • A 题意对齐:逐问输入、输出、指标、约束、验证。
  • B 大纲:按评分友好顺序列出章节与小节。
  • C 评分对齐:评分点与证据映射表。
  • D 模型路线:任务类型/基线/改进/验证/风险与备选。

使用示例

  • 输入:赛题文件路径 c:\path\to\赛题.pdf 或题面文本全文。
  • 行为:读取文档→抽取每问→识别任务类型与数据条件→输出 A/B/C/D 四类结果与建议模型。
  • 自动建议:
    • 基线:选择最简单的经典模型(如线性回归、K-means、最短路算法)。
    • 改进:针对基线不足(如非线性、噪声、多目标)引入的高阶模型(如XGBoost、改进遗传算法、混合模型)。
    • 验证:指标计算、残差分析、交叉验证、灵敏度分析。

防跑偏检查

  • 每问必须给出可量化输出与可验证指标。
  • 符号与单位统一,指标口径一致。
  • 至少一个基线对照与改进证据(提升或更合理)。
  • 结论与图表逐问对应,不“做很多但没回答问题”。

何时不要用本技能

  • 已经明确只需实现某个具体算法或改动单一代码片段时(直接实现更快)。
